This is a really awkward space! What about trying to build a unit into the corner which seems to be dead space. This could house the television and other bits like dvr,amp etc. The unit could then extend out towards the door in length and in height either up to the start of the window or up to the start of the blinds. I would suggest drawers for toy storage and books above. In this way you leave the windows clear for light plus it looks like you have a pull down screen so the tv would be out of the way of that. This arrangement would also hide all those wires and cables! Ikea have some good examples of storage which you could adapt or copy, such as Besta which illustrates the extended toy storage. http://www.ikea.com/gb/en/catalog/products/S39927155/

Beautiful clean modern kitchen! You have a great opportunity to put your personal stamp on the space with a unique backsplash. As you've heard already there are some different approaches. I'd probably place the backsplash up to the wall cabinets and up to the base of the hood. Then continue the backsplash at the same height (18"?) behind the sink. Then place an inspiring colorful picture above the sink to break up the wall. Here's a picture with pendants that aren't too obtrusive. Having multiple levels of lighting at different lumens makes a more inviting feel to the space. I couldn't decipher your flooring, but you may also want to consider adding some nature elements like a type of wood flooring, wood stools, etc. Good luck!

You are correct the place does and always will look a bit sparse when you only have blinds. The question with curtains is sometimes dependant on what climate you live in and I am not sure where you are so I am going to say. If you need curtains for heat go for a quality curtain to the floor with a fabric that is not stiff (as I discovered I now own after buying curtains off line for my spare rooms). The expensive curtains I brought for my living room have a softer texture and hang so much nicer. As I need Curtains / Roman blinds for heat I have backing fabric etc on the expensive made to measure ones, where as the cheaper ones are just thermals. If you only want to add a curtain for looks and do not require it for heat I would recommend going with a lovely sheer / half see through fabric that drapes really well, this will add a point of interest and you can colour match or add a loved colour to a bare - white on white - cream on cream - colour scheme.

I am facing the same thing !! In the same spot Your ideas sound fab. I was going to put a door on mine as I don't have pretty books like you have though. But indent the bifold door 300 in, and make it 600 wide as the hole is 900 then have shelves on one side for some treasures I will start to collect cos I have a place now for them. Do you love the arch or are you going to square it off? Do you love the small one on the left? If not...make it a square niche and modernise them / it, as I'm not a big fan but you may love them. What you propose sounds perfect. The dark colour, nice too..or moody wallpaper on the back wall before putting up the shelves.
